This is the most elegant way I could find to create an thumbnail for an image I want to resize with PHP and Imagemagick. The function will return a filename.
To install imagemagick using Ubuntu, just run
sudo aptitude install php5-imagick

Are you updating an old Django project to use Django 1.2, and getting this error message when you try to login to the Django admin page?
403 Forbidden
CSRF verification failed. Request aborted.
Help
Reason given for failure:
CSRF cookie not set.
Then you need to add ‘django.middleware.csrf.CsrfViewMiddleware’, and ‘django.middleware.csrf.CsrfResponseMiddleware’ your settings.py file. Mine looks like this:
MIDDLEWARE_CLASSES = (
‘django.middleware.common.CommonMiddleware’,
‘django.contrib.sessions.middleware.SessionMiddleware’,
‘django.contrib.auth.middleware.AuthenticationMiddleware’,
‘django.middleware.csrf.CsrfViewMiddleware’,
‘django.middleware.csrf.CsrfResponseMiddleware’,
)
Thanks to the Django docs http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#how-to-use-it

You easily set the default GRUB entry to boot to in in Debian or Ubuntu by editing
/boot/grub/menu.lst
and changing ‘default’ to the number of the record you want to boot from by default. (Note: It is 0 indexed.)
# You can specify ‘saved’ instead of a number. In this case, the default entry
# is the entry saved with the command ‘savedefault’.
# WARNING: If you are using dmraid do not change this entry to ‘saved’ or your
# array will desync and will not let you boot your system.
